Reference the storage via node name rather than inlining it. This is
the approach that will be used with -blockdev/blockdev-add since it

Commit 766d5c1b deprecated the capability, because we were assuming
it for every QEMU binary. At the time of the introduction, there
was no way to probe for this via QMP.
However since QEMU 1.5.0 (which is the earliest version we support)
we can rely on the query-command-line-options command to detect this
feature.

Just like ec982f6d92 denies hugepages for non-existent
guest NUMA nodes in case there are some nodes configured.
Unfortunately, when there are none, qemuBuildNumaArgStr() is not
called and thus we have to have check in qemuBuildMemPathStr()
too.

Some AMD processors only support a non-architectural means of
enabling Speculative Store Bypass Disable. To allow simplified
handling in virtual environments, hypervisors will expose an
architectural definition through CPUID bit 0x80000008_EBX[25].
This needs to be exposed to guest OS running on AMD x86 hosts to
allow them to protect against CVE-2018-3639.
Note that since this CPUID bit won't be present in the host CPUID
results on physical hosts, it will not be enabled automatically
in guests configured with "host-model" CPU unless using QEMU
version >= 2.9.0. Thus for older versions of QEMU, this feature
must be manually enabled using policy=force. Guests using the
"host-passthrough" CPU mode do not need special handling.

These two functions were duplicating some cleanup paths, so let's just merge
both cleanup and error paths together. To distinguish whether we need to
clean-up the return value let's keep it in @tmp until the function is successful
in which case we set @ret to the value of @tmp and set @tmp to NULL.

Historically we matched log filters with strstr(), and when switching to
fnmatch in cbb0fd3cfd, it was stated that
we would continue to match substrings, with "foo" being equivalent to
"*foo*". Unfortuntely I forget to provide the code to actually make that
happen. This fixes it to prepend and append "*". We don't bother to
check if the pattern already has a leading/trailing '*', because
"**foo**" will match the same as "*foo*".
